TECHNICAL FIELD

[0001] The utility model belongs to the technical field of sleeve labeling, especially relates to a bottle clamping mechanism capable of adjusting inclination angle and sleeve labeling equipment. BACKGROUND

[0002] The sleeve labeling equipment has excellent high-speed stability performance. Nowadays, automatic high-speed sleeve labeling equipment has been widely applied in various fields. However, for some containers that are not easy to stand, the containers usually need to be placed on auxiliary mechanisms, such as bases, for conveying. However, for the containers in the bases, a bottle clamping mechanism needs to be used to transit between different conveying mechanisms.

[0003] The existing bottle clamping mechanism has a complex structure and can only be designed for bottles with regular shapes or specific shapes, has poor adjustability, and has a narrow application range. For example, the bottle clamping mechanism cannot complete the bottle clamping action for conical bottles.

[0004] Therefore, it is urgent to improve the bottle clamping mechanism capable of adjusting inclination angle and the sleeve labeling equipment in the prior art, so that the bottle clamping mechanism can be flexibly adjusted to be applicable to containers with different shape profiles or different sizes. In addition, it is desirable to further simplify the structure of the bottle clamping mechanism and improve the operation convenience. SUMMARY

[0006] The above technical problem is solved by a bottle clamping mechanism capable of adjusting inclination angle, which comprises a fixed support and two oppositely arranged bottle clamping modules. The fixed support is fixedly arranged relative to the rack of the sleeve labeling equipment. Each bottle clamping module comprises a conveying belt unit and a driving motor. The bottle clamping mechanism further comprises two supporting members, each of which is fixedly connected to one of the bottle clamping modules. The fixed support has at least one cross beam and two connecting plates fixed to the at least one cross beam. Each connecting plate is pivotably connected to one of the supporting members relative to the other. The bottle clamping mechanism further comprises a locking member for locking the supporting members at a specific position after pivoting relative to the connecting plates. Here, the two bottle clamping modules are oppositely arranged and clamp the bottles therebetween and convey the bottles forward in the clamped state through the conveying belt. The bottle clamping modules are directly or indirectly fixed to the supporting members, that is, the positions of the bottle clamping modules relative to the supporting members are fixed and can move with the movement of the supporting members. Therefore, by adjusting the angle of the supporting members relative to the connecting plates, the angle of the two bottle clamping modules relative to each other can be adjusted, so that the bottle clamping mechanism can be adapted to containers with different profiles.

[0007] According to a preferred embodiment, the stationary holder has two crossbeams, wherein two connection plates are fixed on each crossbeam, the connection plates on the two crossbeams are arranged in pairs flush with each other, and one support is connected between the two connection plates of each pair. By providing two crossbeams and two pairs of connection plates, the stability of the entire bottle clamping mechanism is improved, ensuring the reliability of the bottle clamping even in a vibrating environment caused by rapid operation.

[0008] It is also advantageous that the support is designed in the shape of n, comprising two side walls and a back plate connecting the two side walls, wherein a first through hole is provided on each side wall and a second through hole flush with the first through hole is provided on the connection plate, the side walls are connected to the corresponding connection plates in a rotatable manner by means of a connecting bolt passing through the first through hole and the second through hole, wherein a guide pin protruding towards the connection plate is provided on each side wall and an arc-shaped guide slot cooperating with the guide pin is provided on the connection plate, or a guide pin is provided on the connection plate towards the corresponding side wall, and an arc-shaped guide slot cooperating with the guide pin is provided on the side wall. Here, the connecting bolt functions as a rotating shaft, and the arc-shaped guide slot and the guide pin constitute an inclination angle adjusting unit. The guide pin can be fixed relative to the circumferential side of the arc-shaped guide slot by means of a locking member. The guide pin can be fixedly formed on the side wall or the connection plate, but can also be designed as a detachable bolt passing through a hole on the side wall or the connection plate and passing through the arc-shaped guide slot and thus can be fixed on the circumferential portion of the arc-shaped guide slot by means of a nut.

[0009] It is also preferred that a scale is provided on the outer circumference of the arc-shaped guide slot. This makes each adjustment more accurate and improves reproducibility.

[0010] It is also advantageous that the bottle clamping module is fixedly connected to one support by means of an adjusting mechanism, which comprises a first lead screw nut mechanism arranged transversely and a second lead screw nut mechanism arranged vertically. By means of the adjusting mechanism, the position of the bottle clamping module can be adjusted in the transverse and vertical (height) directions.

[0011] It is also preferred that the stationary holder is fixed on the rack of the labeling device or on the floor. In this way, the position of the stationary holder relative to the main structure of the labeling device can be fixed.

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following is further detailed to the utility model by combining with the drawings and embodiment.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the utility model.

[0021] On the existing labeling line, for some containers which are not easy to stand, auxiliary supports are needed to ensure the containers stand on the conveying path. However, transferring such containers with auxiliary supports between different conveying mechanisms needs to use a bottle clamping mechanism. Usually, the bottle clamping mechanism clamps the containers, and the conveying belt or chain with auxiliary supports is separated from the containers in the transition area, and the separated containers are transferred to the downstream mechanism, such as another conveying mechanism, by the bottle clamping mechanism. In order to adapt to different shapes, such as tapered bottles with a tapered upper end or bottles with a thinner lower end, it is necessary to adjust the angle of the two bottle clamping modules of the bottle clamping mechanism relative to each other to adapt to the external profile of the bottle. Therefore, it is necessary to realize the adjustability of the inclination angle of the bottle clamping mechanism. In addition, in order to adapt to containers of different sizes or different heights, the adjustability of the lateral position and vertical position (height) of the two bottle clamping modules of the bottle clamping mechanism is also urgently needed.

[0022] Figure 1 The structure diagram of the bottle clamping mechanism 100 with adjustable inclination angle in an embodiment of the utility model is shown. Here, the bottle clamping mechanism 100 includes a fixed support and two oppositely arranged bottle clamping modules 3. The fixed support includes two cross beams 1, but can also have one cross beam or more cross beams. Here, the fixed support is fixedly arranged relative to the rack position of the labeling device, such as fixedly connected with the rack or fixedly arranged on the floor. The cross beam 1 includes two downward extending connecting plates 2 respectively. Although two connecting plates are shown here, one or more than two connecting plates are also possible. However, the scheme of two cross beams and two connecting plates on each cross beam is preferred, which on the one hand realizes good stability, and on the other hand the structure is relatively simple.

[0023] The two bottle gripping modules 3 are arranged opposite to each other and have a not shown bottle clamped in between. The bottle in the clamped state is transported forward by a conveyor belt. The bottle gripping modules 3 comprise a conveyor belt unit 7 and a drive motor 5. The conveyor belt unit 7 is for example fixed between an upper cover plate and a lower cover plate, on which the drive motor 5 is fixed. The surface of the conveyor belt of the conveyor belt unit can advantageously be designed with a surface structure for increasing the friction. The conveyor belt unit forms together with the two cover plates and the drive motor a preassemblable unit, which is easy to install. The bottle gripping mechanism 100 further comprises two support members 4, each of which is fixedly connected to one of the bottle gripping modules 3. For example, the upper cover plate for the conveyor belt unit 7 of the bottle gripping module 3 is fixedly connected to the support member 4. Between the upper cover plate and the support member 4 there can be a direct connection or there can be an intermediate adjustment mechanism, for example an adjustment mechanism 6 for adjusting the horizontal or vertical position. The connection plates 2 are pivotable relative to the support members 4 and can be locked in a certain position after pivoting. That is, the bottle gripping mechanism 100 further comprises a locking member for locking the support members 4 in a certain position after pivoting relative to the connection plates 2. The position of the bottle gripping modules 3 relative to the support members 4 is fixed and moves with the support members 4. By adjusting the angle of the support members 4 relative to the connection plates 2 the angle of the two bottle gripping modules 3 relative to each other can be adjusted, so that different profiles of containers can be adapted to.

[0024] In the shown embodiment the support members 4 are designed as n-shaped and comprise two side walls and a back plate connecting the two side walls. However, it is clear that other shapes are possible, for example an I-shape. On the side walls first through holes are provided, on the connection plates 2 second through holes are provided, which are aligned with the first through holes, and the side walls are connected to the respective connection plates 2 in a pivotable manner by means of a connecting bolt, which passes through the first and second through holes. The connecting bolt can be used as pivot axis. Further, on each side wall a guide pin is provided, which protrudes towards the connection plate 2, and on the connection plate 2 an arc-shaped guide slot 8 is provided, which cooperates with the guide pin. Vice versa, it is also possible to provide a guide pin on the connection plate 2, which protrudes towards the respective side wall, and an arc-shaped guide slot on the side wall, which cooperates with the guide pin. The arc-shaped guide slot and the guide pin form an inclination adjustment unit. The guide pin can be fixed relative to the circumference of the arc-shaped guide slot by means of a locking member, so that the bottle gripping module 3 is fixed in a certain position with a certain inclination. The guide pin can be fixed in form on the side wall or the connection plate, but it is also possible that the guide pin is designed as a detachable bolt, which passes through a hole in the side wall or the connection plate and through the arc-shaped guide slot and can thus be fixed by means of a nut on the circumference of the arc-shaped guide slot. The locking member can for example be a nut or another latching member.

[0025] In order to achieve accuracy and reproducibility of the adjustment, a scale can advantageously be provided on the circumference of the arc-shaped guide slot 8. Figure 1It is further shown that the bottle clamping modules 3 are fixedly connected to the support 4 by means of an adjustment mechanism 6. The adjustment mechanism 6 is used to adjust the position of the bottle clamping modules in the lateral and vertical (height) direction.

Figure 2 It can be clearly seen that the inclination angle adjustment unit formed by the arc-shaped guide slot 8 and the guide pin. The connecting bolt 9 rotatably fixes the bottle clamping module 3 to the connecting plate 2. The connecting bolt 9 forms the rotation axis between the connecting plate 2 and the support 4. The bottle clamping module 3 comprises a conveyor belt unit 7 arranged between the upper cover plate and the lower cover plate and a drive motor 5 fixed to the lower cover plate. The bottle clamping module 3 is fixedly connected to the support 4 as a whole.

[0027] Figure 3 A side view of the aforementioned bottle clamping mechanism with adjustable inclination angle is shown. Figure 3 The structure of the adjustment mechanism 6 is clearly shown. Here, the bottle clamping module 3 comprising the drive motor 5 is fixed to the support 4 by means of the adjustment mechanism 6. The support 4 can be swung around the rotation axis relative to the connecting plate 2 and can be fixed in a position with a certain inclination angle by means of a locking element, such as a locking nut. The adjustment mechanism 6 can comprise a first screw-nut mechanism arranged in the lateral direction and a second screw-nut mechanism arranged in the vertical direction. Obviously, the adjustment mechanism can also comprise other assemblies for converting rotation into translation, such as a gear rack, a worm gear mechanism, etc. In order to facilitate the adjustment of the lateral or vertical position, the exposed end of the screw rod of the first screw-nut mechanism and / or the second screw-nut mechanism is fixed with an operating wheel, not shown. The user can conveniently adjust the lateral position and / or the height of the bottle clamping module 3 by means of the operating wheel.

[0028] The utility model further provides a sleeve labeling equipment, the sleeve labeling equipment includes the bottle clamping mechanism with adjustable inclination angle of any embodiment described above.

[0029] In summary, in the embodiment, the inclination angle of the support relative to the connecting plate can be adjusted to adjust the angle of the two bottle clamping modules relative to each other, so as to adapt to containers with different profiles. Thus, the conveyors of the two bottle clamping modules cooperating with each other can better fit the profile of the container to achieve better clamping effect. In addition, by providing an adjustment mechanism between the support and the bottle clamping module, the position of the bottle clamping module in the lateral and vertical directions can be adjusted.
